ment see fig. 22.
Optocouple Inputs
The module Pro II-MIO-4-ET1 Rev. E provides 4 channels of optically isolated
digital inputs. The input voltage range can be set by jumpers (5V, 12V, 24V).
The default setting of the input voltage range is 24V. The switching time of only
100ns allows the sampling of high-speed digital inputs.
Each channel is optically isolated from the system circuitry and from the other
inputs. The event-input is optically isolated from the system as well.
Please not that
EXT
GND
is also used for transistor outputs.
The inputs are provided on the 25-pole D-Sub connector

ment see fig. 22.

SSI Decoder
An incremental encoder with SSI interface can be connected to the decoder.
The signals are differential and have RS422/485 levels.
You can set the clock rate (6kHz … 12.5MHz) as well as the data resolution
(up to 32 bit) of the decoder via software.
A decoder either reads out an individual value (on request) or continuously pro-
vides the current value.
Via the two pins
U1
IN
you can supply a voltage, which is then available at the
pins
U1
OUT
e.g. for external incremental encoders. The maximum current at
each of the output pins is 100mA; there is an appropriate fuse between each
input and output pin.
